Linear and Quadratic Functions: Determining a Quadratic Function

Presentation Tutorial: Writing the Quadratic Function Using Roots and the Vertex

Suppose you are given the roots of a quadratic function and one point on the graph, the vertex. How could you write the quadratic function from this information? In this tutorial we will go through an example of how to find the quadratic function given roots and the vertex.  Select the play button to begin the tutorial, and then use the navigation buttons to pause/stop, continue, or reset the tutorial.  View the presentation as often as you would like, and take notes as you follow along.  Be sure to set your volume at a reasonable level before you begin.
